I am aware that springs have been used heretofore for the purpose of completing a circuit automatically after passing a deadpoint, so I do not claim, broadly, the invention of that part of the switch; nor do I limit myself to the precise circuits shown, as it is obvious that many different arrangements of circuits may be operated therewith; but

That I claim as new, and desire to secure by Letters Patent, is-.

l. In a combined switch and telephone support, the combination of a fixed post and a pivoted lever provided with contact points the post and the lever being set so as to form a lock when the switch is in one extreme position and so that their outer ends are brought nearly together when the switch is in the other extreme position, and a telephone provided with a ring or equivalent actuating mechanism whereby it is sustained bythe supportand operates the switch, substantially as described.

2. The combination of a T- shaped circuit changing switch A,B, C, curved up at its outer end, circuit terminals D, E, pivot G, spring Il, post J, and ring r, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 30th day of November, 1894.

GEORGE FREDERICK SIIAVER.
